URGENT: At least 14 people have been killed and up to 50 injured after a mass shooting at a showing of “The Dark Knight Rises” at a suburban Denver movie theater, police say.

The suspect, believed to be the lone gunman, is in police custody. KUSA reports that the suspect kicked down an emergency door at the theater, threw in some type of a smoke bomb and when moviegoers started to run, he began shooting.

Witnesses say they heard a series of explosions and up to 20 gunshots after the scene grew chaotic. About 100 witnesses were taken to a local high school to be questioned by police.

Police, ambulances and emergency crews swarmed on the Aurora, Colo., theater after frantic 911 calls around 12:30 a.m. local time, officials said.

The suspect reportedly fired shots inside the theater and fled to the parking lot and was confronted by police already at the theater for crowd control.

The suspect’s identity was not released, but was wearing a bullet-proof vest and in his 20s, police said. The gunman was carrying a rifle and two handguns, police said. The handguns may have been placed in the theater before the shooting.
